Power Lumbar
WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The driver seat has an electro-mechanical backrest pad adjuster mounted to the backrest frame to provide more lower body displacement. The lumbar switch is located on the side of the seat cushion. The power lumbar includes an electric air compressor and air bladder that inflates or deflates to move the backrest foam pad in and out for lumbar support adjustment.
